Abstract

Five females, six restores and the resultant 30 F1 hybrids along with three checks (CSH 22SS, PAC 52093 and NSSV 13) were evaluated for their sugar and grain yield stability at three locations during Kharif 2010. The experiment was laid out in Randomized Block Design (RBD) with three replications. A major portion of Genotype × Environment interactions was linear for total soluble solids, total sugar index, total biomass, juice yield, grain yield and ethanol yield reflecting the predictable performance of genotypes over environments. Based on stability parameters and over all mean the hybrid, NSS 1007A × CSV 19SS for total soluble solids and NSS 8A × RSSV 120 and NSS 1016A × RSSV 76 for total sugar index were the best stable hybrids with high mean yield.
